Installers and system integrators must consider a wide range of readers and credential types in the evaluation process when designing an access key lock control system. Determining the appropriate solution for an application will depend on a needs assessment conducted with the end user to define specific functionality, compatibility and operational criteria for the new system. Among the products that may be considered are legacy card readers, keypads, keycards, integrated lock devices, proximity readers and biometric technologies—and all the credentials each of these devices will require.

When it comes down to a final decision on access control technologies, one key question is, which of these products and/or combination of devices delivers the accuracy, security and cost-efficiency to best meet your defined system criteria and budget?

Before exploring mandatory access control the answer to this question, it’s important to understand the basic concept of identity, which affects nearly every aspect of security.

Identity is particularly vital with access control, where the decision to allow an individual to enter any secured area depends on the ability to determine if he or she is authorized to be there. Therefore, physical security depends on the ability to connect authorities and permissions to the particular individuals who hold security lock them. This connection between identity and permission is critical for triggering actions, including opening a particular door, admitting visitors, issuing keys, accessing sensitive or valuable materials and more. This is why identity verification in security systems—and particularly access control systems—is so important.
